IMPROVEMENT IN MACHINE FOR PUTTYING SIE-AMS OF VESSELS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

Be it known that I, ALFRED STEVENS, of Georgetown, in the county of Sagadahoc, and State of Maine, have invented a new 'and useful Improvement in Machines 'for Iuttying the Seaxns of Vessels; `andI do hereby declare the following to be a full, clear, and

exact description thereof,suiicient'to enable those' skilled in the art to which my invention appertains, to fully understand the same, reference being had to the accompanying drawing, forming part of this specification, and in' which-- .Fgnre l is a side view, in partial section,

Fieure 2 is an inverted plan view, andv Figure 3, a transverse section of the improved seamputtying machine, the planeof section being indicated by the line :v x in fig. 1.

The subject of this invention is a machine or device, to be operated by hand, for filling the seams of vessels with putty.

The invention comprises several improvements on a seam-pnttying machine for which. Letters Patent of the UnitedStates, bearing date August 3, 1869, and` numbered 93,365, were granted to me as assigner tol Josiah Starling. In the device referred to, the block or frame formingthe body of the machine is made square at the ends, and so is the cavity in the block or frame. It has been found .that this construction made the machine unnecessarily-heavy, espcciall y when the block is of cast-metal.

`One of my present improvements consists in rounding the ends of the block, and also its inner end. faces, so that the weight is considerably lessened, and, at the same time, the operationof the machine is rendered more effective.

Another feature of improvement, in the present case, consists in making the block, frame, or body of the machinein two parts, and connecting -t-hem together by means of pivoted links, whereas, in the formerl case, theblock was made entire.

The advantage gained by this improvement is, the play allowed the scraper, whereby it may conform to all the irregularities of snrfaceover which it may pass,

aspring being provided, which presses on the part to which the scraper is attached.

In order that' others may so understand my invention as to be able to make and use this device, I will p now proceed to describe it in detail.

Referring to the drawing, in the several figuresof which similar letters of reference indicate like parts- A is the main portion of the machine, made of wood or metal, and having rounded ends, as clearly shown.

A cavity, the formrof which is shown by dotted lines in iig. 1, is formed in the part A.

It will be seen that the dotted lines a c, representing the inner faces of the block, and the outer ends of the part A, arc on the same curve.

, In the bottom of part A is made a rectangular opening, in which are set .two strips, B B, which are secured by screws b b, or in any other suitable manner.

c c are thin plates of metal, (tin, sheet-iron, or stcel,) which I call tires These plates are fitted, as shown, over the strips B, and are secured thereto at dfd, and bent'down ,over the inside of the strips, so as to pyroject below, thus leaving the tires free to play in the seam of the vessel. i

In order to adjust the tires to seams of various widths, thumb-screws b b' are provided, which work through the strips B B, and the sides of the part A,

and press against the tires, as shown in figs. 2 and 3, G represents agauge, of wood or metal, fixed in a groove iu the bottom of part A, and projecting in front of the same. The oliice of this gauge is to clear out the seam, `or pressdown the former filling, in advance of the tires, and tothe same depth as they extend.

E E are followers, hinged together at f, the rod g, which connects the leaves of the hinge, being fitted in the sides of the box or part A, as shown in iig. 3.

These followers or. blocks E are each provided with a lever,.F.

Thefollowers E, when pressed down, force the putty, with which the part or box A has been filled, out between the tires, and into the seam.

Springs h h. are secured to the followers, to perfect their operation.

I) is a presser or smoother, set ina groovelin thebottom of part A, in line with the gauge C and tires. This device compresses and smooths the putty in the seam.

G represents a block, which is partially hollow'ed.

out, as shown in figs. l and 2.

This block is coneeted to the main part A by means of pivoted links i t'.

H is a metallic scraper secured within thepart G, l

and is used to make the putty smooth and even inthe seam.

f The object in attaching the part Gto the main frame by means of pivoted connections is to give the scraper and finishing-smoother sufficient play to allow them to conform Ato the inequalities of surface over which it may pass.

In order to keep the part G, with its attached de'- vices, down to its work, a spring, It, Vis employed,'which is attached to the lever oi the iear follower E, andy presses on the top of' the said block G, a space, l, being left in the rear end of the part A, to receive the spring k when the lever is fully depressed.

'The operation is as follows:

The sides, ends, and bottom ofthe cavity in the part A are first well oiled, and the space is then filled with putty, the followers E being elevated, to give room for that purpose. The tires are now adjusted according to the size of the seam to be filled. The machine is then applied to the seam, the levers being held in the hands, the gauge, tires, and presser fitting in the seam. Now, move the machine steadily forward, at the same time pressing on the' levers, and thereby forcing the putty down, through the opening between the tires, into the seam below, which has been prepared for its reception by the gauge. The tires, being flexible, will conform to all inequalities in the seam, and fill every part with putty, the first smoother will compress landV harden the putty in the seam, the se; aper removes all that remains outside on the edges, the detached scraps falling into the refuse-box, and the rear smoother will finish oft' the operation, leaving the-putty smooth and even in the seam.

Bymeans of this machine, the operation of putty- What'I claim as new, and desire to secure by Let- 1. The part G, which carries the scraper, finishingsmoother, and refuse-box, when connected to the main part A by means of pivoted links, substantially as herein described and shown, for the purpose specied.

\2. In a seam-pnttying machine, the spring attached to the lever F, and pressing on the block G, substantially as described, for the purpose set forth.

3. The seam-puttying machine herein described, composed of the part A, with rounded ends, and a receiving-cavity of the form described, the gauge, adjustable tires, followers E E, with levers F, and springs, the presser I), part G, with refuse-box, scraper, and

finishing-smoother, and the pivoted links i, and-spring k, all' combined and arranged to operate substantially as herein shown and described. v
